I have a HP Pavilion dv7 Notebook running Windows 7 Home Premium SP1
am running AVG Internet Security 2012 I am connected to wireless and a LAN connection on a home network Both connections show connected with internet access.I can send and receive emails on Thunderbird and access banking on Quickbooks but cannot open any web pages on firefox or IE. I Firefox and IE set for allow all on avg firewall but when i try to connect the firewall log shows it as a blocked connection. Any Ideas?

I've not had this problem with AVG for a while, but it has happened occasionally. Unfortunately, I don't have a reference copy on a machine at present (my AVG-loaded reference box is loaned out). I wonder, however, if there is still a 'reset configuration' button for the firewall like there was in AVG 2012. That should allow the firewall to begin learning connections over again.

I've not had the issues with AVG some mention here, and it is one that my clientelle uses. We have also had good luck with VIPRE which has good 'firewall training' and manual configuration options. I've used it with both standard machines, and some with custom POS applications running peer-to-peer in mixed Win7 and XP environments successfully. Its method of protection is different, which sometimes leads to mixed reviews, but I've had no machines become infected (including those that are heavy users of online gaming).

Popular White Paper On This Topic

Are you running IE through a proxy server? Most people do not use proxy servers for general browsing unless your vpn'd into work then you would use a proxy server. Check to see if you have IE set to use a proxy and if you are, try disabling it and see if you can open web pages then?

Looking at the menu bar, choose tools, Internet options, then you need to choose connections tab, and then on the lower part of that page, choose Lan Settings. You will get a pop-up window "Loca Area Network (LAN) Settings" and inside that box there are two boxes at the top of that pop-up window, automatically detect settings, or use automatic configuration script. If you are NOT using proxies, then you should choose the first box "Automatically detect settings" and make sure that in the lower section of this pop-up window where it says "Proxy Server" that you do NOT have the check box. "Use a proxy server for your LAN blah blah blah" selected... If it is selected then un-check that box.

If IE still doesn't work, have you tried running Firefox or Opera, do these work? You would want to try these other browsers to eliminate any issues with IE and your firewall settings.

Lastly, what version of IE are you trying to use? If its old, then that could potentially cause some issues. I absolutely HATE IE and I delete off of every machine I have built. I refuse to use it . I use Firefox. its awesome and it just always works.

I have the same machine and the same thing drove me mad, i dont like IE so uninstalled it, same with AVG, downloaded AVG removal tool and i use Microsoft security essentials, just my preference but i can now use whatever search provider without any problems

If it's not the proxy settings and nothing you do seems to work then
you'll need to remove AVG totally and then re-install. Have seen this
before and usually messes up after an update that doesn't go well,
this then prevents further updates so AVG cannot fix itself.

@Mark Durney, Your obvious interest in helping others is to be commended, just a few points, the little things that help you assist a bit more clearly...

And, Chad had indicating in his OP that he did in fact use both IE and Firefox. It's important for all of us, not just the OP, to see that you have read and understood his query fully.

Just a word to the wise
And thank you for you contribution

Hi ,thanks all, for your replies @ BurtonTech if I disable Avg firewall
(and with firewall disabled i can browse on IE and Firefox) I was able
to update AVG, then turn firewall back on, after that it all worked for
a couple minutes then the same problem ( will it make any difference if
I uninstall and reinstall?)
@Mark browsers are NOT set to proxy
@Marc I followed your link and sent the info on to AVG so am waiting for
reply from them
@stepheneastwood I don't use IE either just haven't ever erased it, am
waiting to hear back from avg before i change antivirus

Get rid of AVG, its getting to be Nortonesque, i.e. bloated and clunky with way too many false positives. If you want a firewall use Comodo or Zonealarm, personally on a Windows PC I'd use Zonealarm, its been at the top of the firewall game for years and years and for good reason.

For antivirus Microsoft Security Essentials isn't bad, or Avast. both of these are system light.

Hi, I did reset the firewall configuration...same problem. Will wait and
see if AVG has any solutions ( if they get back to me) if they can't
help, and probably in the long run, I'll do what some of you either
hinted at or said outright, get rid of AVG. Thanks all will keep you posted.

I use AVG all the time, on many of my PCs and I have never had any issues.

What do you have set up with regards to AVG? Did you go into advanced settings and make a lot of changes in an effort to make the PC more secure? Have you tried just running the firewall with the default settings? That's all I use and again I have not had any issues. I use the business version of avg and it has been solid.

From that I'd surmise that the AVG firewall is corrupted in some way
and the best option would be to erase AVG totally using their removal
tool and then install from scratch. Your existing licence term will be
picked up when you enter the key so you'll not lose out.

BTW - I agree with others that AVG is becoming somewhat of a resource
hog and maybe it would be worth investigating alternatives for when
your current licence term is up. I've been installing Panda Cloud Free
for customers and this is very light on resources so maybe the paid
version of this is worth a look ?

I guess I failed to to restart the computer after resetting the firewall
:( After I restarted the system it is all working again for now at
least. Thanks Debra and all the rest for your time and Info.

Remember, it's a tech secret. At least that's what I tell my users with a smile. I hope they let the secret out.
I also have about 450 wyse terminals. Those lock up. The saying then is 'it doesn't work now, go ahead and kill power, then reboot.'

HA> Not exactly a secret. The "IT Crowd" series on BBC had an entire
HA> sequence that showed them answering every call with "Did you turn
HA> it off and then back on?".

One of the first things I'll say too when a customer rings up with a
malfunctioning computer or peripheral - amazing how many glitches are
fixed by this and how many times the fix isn't temporary too !! If a
total power cycle of everything doesn't do it, or the same problem
returns soon, then it's onto fault finding as usual :-)
